It all started with that Seattle grunge crap ... Radio? I wouldn't even know. "... Give me some Motley, shout at the devil, please, 'cause that Amy Winehouse, just doesn't do it for me ..." - Johnny Lima (Give Me Some Rock So I Can Roll)
Depends on what you like, but there ate some great new bands bringing back the hair metal of the 80's, check out Halestorm for example.
Music has gone down hill because big corporations pick a person and make them famous rather than the person or bands ability to sing, or use an instrument. Gone are the days when bands used to practice in the garage, cut a demo and then hit the pavement trying to get radio stations to play their music. now all you have to do is get on line at an american idol audition. Technology has also lead to the destruction of a lot of good music being heard. You use to buy the whole album. Now people just download individual songs that are usually over played on the radio, never listening to the less popular, but often better songs on an album. Believe it or not I enjoy listening to records, cassette tapes and cd's for that reason
